AGC's President and CEO Al Hasse said Sunday that reports of recent behavior by one of his unit executives is "offensive and disturbing."

"We have taken this matter very seriously and worked diligently to examine it since learning of the matter on Friday afternoon. As of Sunday, the executive is no longer employed with the company," Hasse said.

Hasse went on to say that such behavior is contradictory to the company's values. He said it was "embarrassing and does not in any way reflect the patriotic character of the men and women of diverse backgrounds who work tirelessly in our business."

AGC spokesman Daniel Keeney of DPK Public Relations told ABC News, "Since this is a personnel matter, we can't describe further the specifics of Mr. Hundley's departure from the company."

Hundley was on a flight from Minneapolis-to-Atlanta, set to land at Hartsfield-Jackson International Airport on Feb. 8, according to an FBI court affidavit. He was sitting next to Jessica Bennett and her 19-month-old son, who began crying as the plane started to descend.
